SELF-EXTINGUISI-IING LAMP.

Specification of Letters Patent.

Patented Dec. 31,1912.

Application filed March 20, 1912. Serial No. 684,932.

To all whom it may concern:

Be it known that I, CARL T. SIEBERT, a citizen of the United States,residing at East Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inSelf-Extinguishing Lamps, of which the following is a specification,reference being had to the accompanying drawing.

This invention relates to lamps or lanterns and more particularly tothat class which are self extinguishable.

The object of this invention is to provide a lamp or lantern which willbe put out or extinguished automatically in case the lamp is knockedover.

A further object is to have the lamp arranged so that the partsembodying this invention can be gotten at without difliculty for anypurpose whatever.

Another object is to have the construction of the invention as simple aspossible so that its cost of manufacture and installation will be small.

Other objects of this invention will be come apparent as it is morefully set forth.

This invention consists in general of an attachment which is slippedover the wick tube of an oil lamp or lantern'and is held in placethereon by means of small weights. These weights will be easily detachedfrom the attachment when lamp or lantern is upset, and on the removal ofthe weight a spring acting on the attachment moves the same over thewick and puts it out should it be lighted.

In the accompanying drawings which illustrate by way of example, anembodiment of this invention, Figure 1, is a view in elevation of amodification of this invention in normal position, the dotted outline,showing the attachment parts in extinguishing position. Figs. 2 and 3,are details of the attachment parts. Fig. 4 is a plan view of Fig. 1.

Similar reference characters refer to simi lar parts throughout thedrawings.

In the construction 1, represents a conventional lamp burner base, whoselower position 2, is adapted to threadably engage in the ring 3 of alamp reservoir 1. A cap 5 is provided for the base and is arranged so asto be readily removed therefrom so as to permit easy access to the wicktube 6. Suitable mechanism 7, is provided in the base for controllingthe lamp wick 8. Mounted on the wick tube 6, is an attachment sleeve orcasing 9, which is arranged to slip over the tube easily being alsoprovided with a hole in its upper portion to permit the wick to extendthrough it. A pair of arms 10, having cup shaped extremities 11 areattached to opposite sides of the casing and form means for retaining apair of balls or weights 1:2 therein for keeping the sleeve or casing 9low down on the wick tube, so that it will not interfere with the wickof the lamp in any way. Attached to the casing.

and tending to press the same upwardly, so as to cover the wick, is acoiled spring 13 which surrounds the casing 9 and presses on the upperplate 14 of the burner base. Normally the sleeve or casing 9, is keptclose to the burner base by reason of the weights 12, but on the latterhaving rolled out of the parts 11, they will remove the resistanceoffered to the spring 13, which will raise the casing so that it willcover the wick sufiiciently to cause the light to go out.

Obviously while I have shown but one form of this invention in thedrawings, I do not wish to be limited to that particular form or in anyother way, otherwise than anticipated by the .prior art, as manymodifications of this invention may be made without departing from theprinciples thereof.

Having thus described my invention, I claim:

1, In combination with a lamp burner a wick tube attachment comprising asleeve adapted to embrace and rest on the wick tube of the burner andits body proper and formed to closely surround a wick in the wick tube,resilient means engaging with the base of the burner and acting on saidsleeve tending to close it over the wick, a pair of arms on said sleevefor retaining the means against the sleeve and free weights in said armsadapted to act against said means when the lamp is positioned in itsnormal position.

2. In combination with a lamp burner a wick tube attachment comprising asleeve adapted to embrace and rest on the wick tube of the burner andits body proper, and formed to closely surround a wick in the wick tube,a coiled spring for raising said sleeve over the wick, a plurality ofU-shaped arms attached to said sleeve and arranged to keep the springadjacent to said sleeve and provide means for the same to act on wherebythe sleeve can be raised over the wick, a plurality of cups disposed onthe arms, said cups being arranged to rest on the body proper whennormally positioned, and a plurality of free weights disposed in thecups adapted to fall out of said cups when the burner is tilted from itsnormal position.

3. In combination with a lamp burner having a cap, a wick tubeattachment comprising a sleeve adapted to embrace and rest on the wicktube of the burner and its body proper, and formed to closely surround awick in the wick tube and adapted to reciprocate through the cap, acoiled spring for raising said sleeve over the wick, a plurality ofU-shaped arms attached to said sleeve and arranged to keep the springadj acent tosaid sleeve and provide means for the same to act on wherebythe sleeve can be raised over the wick, a plurality of cups disposed onthe arms, and a plurality of free weights disposed in the cups adaptedto fall out of said cups when the burner is tilted from its normalposition and means for con trolling the movement of the balls from thecups.

4. In combination with a lamp burner of the class described, having acap, a Wick tube attachment comprising a sleeve having a portion thereofrestricted and adapted to embrace the wick of the burner and rest on itswick tube, the remaining portion of said sleeve being arranged to slideover the wick tube and restrict the movement of the sleeve, a pluralityof U-shaped arms having one ct their legs attached to the secondmentioned portion of the sleeve and extended alongside of the restrictedportion, cups attached to the end portions of the remaining legs of saidarms and adapted to come adjacent to the body proper of the burner, freeweights for said cups, ears on said cups for controlling the frictionalhold of the cups on the weights, and resilient means resting on the bodyproper and disposed between the legs of the arms for raising the sleeveover the wick when the attachment is unrestrained by said weights.

In testimony whereof I hereunto atTiX my signature in the presence oftwo witnesses.

CARL T. SIEBERT.
